Definitions
- a PCMCIA wireless modem card has an antenna which transmits and receives signals.
- the overall performance of the antenna is a function of the length of the antenna. If the antenna is extended and then rotated or pushed back into the PC card rather than in full extension, the performance of the modem card is compromised.
- a retractable antenna device is disclosed that is used with a personal computer to provide wireless communication.
- a device for providing wireless communications includes a PC card, a modem within the PC card, a retractable antenna connected to the modem, the retractable antenna having an extended transmitting/receiving position and a retracted position with respect to the PC card, and a locking mechanism for providing a lock to maintain the antenna in the extended position during ordinary use and retraction of the antenna when not in use.
- a retractable antenna for a PC card for use in wireless communication includes an antenna sleeve electrically connectable to the PC card, a retractable antenna positioned within the antenna sleeve and slidable within the antenna sleeve from an extended transmitting/receiving position to a retracted storage position, and a locking mechanism provided between the antenna sleeve and the retractable antenna for locking the antenna in the extended transmitting/receiving position to achieve a predetermined transmitting/receiving antenna length.
- the PCMCIA card will transmit and receive radio signals in the 1850 to 1990 megahertz ranges.
- the retractable antenna has a pivotable connection for pivoting the antenna about a first axis and a rotatable connection for rotating the antenna in direction which differs from the direction of pivot of the pivotal connection.

- Four axial slots 26 on the antenna body 20 form four fingers 21 and allow the antenna body 20 to be squeezed into the antenna sleeve 22 .
- the antenna sleeve 22 has a neck 28 on the proximal end that is ring shaped with an inner diameter smaller than the inside diameter of a remainder of the sleeve. The neck 28 of the sleeve 22 snaps into a locking groove 25 of the antenna body 20 when the antenna is in the extended and locked position.
- FIG. 4 is a cross-sectional view of the antenna body 20 and antenna sleeve 22 in the locked position where the four fingers 21 on the antenna body have been squeezed into the antenna sleeve and the neck 28 is snapped into the locking groove 25 .
- FIG. 5 illustrates one embodiment of the antenna 12 , which pivotally rotates about a pivotal connection 30 from the extended position of FIG. 2, shown in phantom lines as 12 ′, to a raised position where the antenna has been moved in a direction of arrow B.
- the pivotal connection 30 enables a user to adjust the position of the antenna 12 with respect to the PC card 14 .
- the pivotal connection 30 may comprise any suitable means including, but not limited to, a hinge, such as a tongue-in-groove hinge.
- the pivotal connection 30 allows the antenna 12 to pivot about an axis of the pivotal connection.
- the matching circuit comprises an inductor/capacitor (LC) circuit.
- LC inductor/capacitor
- FIGS. 5-7 illustrate one embodiment of the PC card 14 .
- the PC card 14 includes a top portion 46 , a bottom portion 48 which is attachable to the top portion, electrical components which are entirely enclosed by the top and bottom portions, and channel portions 50 located in the top and bottom portions. Also, shown is a PCMCIA connector 52 .
- FIG. 6 shows the top portion 46 having corresponding openings 58 , which receive the alignment pins 54 when the top and bottom portion 46 , 48 are attached to form a housing 60 for the PC card 14 .
- FIG. 7 illustrates the bottom portion 48 of the PC card 14 having at least one alignment pin 54 which extends from an inside surface 56 of the bottom portion. (FIG. 7 shows three alignment pins)
- the top and bottom outside surfaces 62 , 64 of the top and bottom portions 46 , 48 are substantially coated with a conductive material to provide shielding for the electrical components located inside the PC card 14 .
- the top and bottom portion 46 , 48 are preferably otherwise formed of plastic.
- a cut out portion 76 is provided in the top and bottom outside surfaces 72 , 74 adjacent to the sleeve 22 , which supports the antenna 12 when the antenna is extended. The cut out portion 76 electrically separates the conductive shielding material and the sleeve 22 .
- the inside surfaces 56 , 60 of the top and bottom portions 46 , 48 are coated with a conductive material to provide good shielding for the electrical components located inside the PC card 14 .
- the passage 78 in the sleeve 22 is configured to slidably receive the antenna 12 .
- the end cap 38 mounted at the distal end 40 of the antenna portion 36 has an outer diameter larger than the inner diameter of the passage 78 of the sleeve 22 .
- the end cap 38 prevents further insertion of the antenna 12 into the PC card 14 beyond a predetermined distance.
- the end cap 38 provides a means for the user to grasp and reciprocally move the antenna 12 between the retracted position and the extended position.
- a conductive member 82 is provided in the PC card 14 adjacent to the sleeve 22 .
- the conductive member 82 is connected to electrical components enclosed in the PC card 14 .
- the conductive member 82 may comprise any suitable means including, but not limited to, a torsion spring, a leaf spring, or a cantilever member.
- the device functions to receive and transmit electrical signals to and from the PC card 14 .
- the antenna 12 When the antenna 12 is in the retracted position, the channel portions 50 of the PC card 14 substantially receive the antenna. Further, the antenna portion 36 , covered or wrapped with a nonconductive material, is adjacent to the sleeve 22 .
- the antenna 12 does not have electrical connection with the antenna sleeve 22 when in the retracted position.
- the antenna portion 32 By slidably moving the antenna 12 from the retracted position to the extended position, the antenna portion 32 , formed of a conductive material, contacts the sleeve 22 , wherein a signal can be transmitted from electrical components enclosed in the PC card 14 through the conductive member 82 to the sleeve 22 and then to the antenna 12 .
- the antenna 12 can pivot about the pivotal connection 30 and can rotate about the X-axis so that the antenna may be moved into the most appropriate position to maximize the effectiveness of use.
- the length of the antenna in the locked and fully extended position is a function of the PCMCIA card's operating frequency.
- the operating frequency of a PCMCIA card is the number of cycles in which a radio wave is transmitted and received.
- the frequency is measured in hertz. One hertz is equal to one cycle per second.
- the relationship between a radio signal's frequency and its wavelength in meters is calculated using the formula:
- Wavelength (m) 300/frequency
- the PCMCIA card will transmit and receive a radio signal in the 1850 to 1990 megahertz ranges.
- the length of the antenna in one embodiment would be one half of a wavelength based on the operating frequency calculated in wavelengths or 0.08 to 0.075 meters. If the frequency of the PCMCIA card is 800 to 900 megahertz, the length of the antenna is 0.375 to 0.333 meters. Thus, in a preferred embodiment, the length of the antenna will be a fraction of a wavelength which maximizes performance of the antenna.
- the antenna preferably can be extended or retracted between the locked and unlocked position with a force of between 250 and 850 grams. In other words, a force of at least 250 grams is required to disengage the snap lock provided by the neck 28 and the locking groove 25 .
- the locking retractable antenna for use with a PCMCIA card is designed to lock into place when the antenna 12 is fully extended maximizing the receiving and transmitting capability of the modem. Furthermore, in the retracted position the antenna 12 is substantially received by the PCMCIA card.
- the PC card 14 shown in the figures is a PCMCIA Type II card, but it is within the scope of the invention to use a PCMCIA Type I or Type III card, as well. Likewise, it is within the scope of the invention that the PC card 14 can be any of a variety of removable cards that are not restricted to the PCMCIA standard specifications.
